To all whom t may conce/m.'

Be it known that I, GEORGE V. BAILLARD, a citizen of the United States, and a resident of New York city, in the county of New Yori; and State o'f New York, have invented certain new and useful Improvements in VehicleTires, or" which the following is a speeication.

My invention relates to vehicle tires, and the .object of my invention is to provide a tire for vehicles of the pneumatic type havingr a plurality .of expansible sacks which may be inflated with air simultaneously, and having means for closing the communicating passages te provide a tire having separate pneumatic chambers located adjacent to each other and extending all around the periphery to form a continuous tread.

Further objects will be pointed out hereinafter and the novel features of construction pointed out in the claims.

Better-ring to the drawings which form a part of this specification Figure l is a cross see-tional view of a tire embodying my invention. Fig. 2 is a longitudinal view shown partly in section of a portion of the tire mounted on a section of a wheel. Fig. 3 is a cross sectional view through the conduit and one of the passages leading to one of the tire chambers, illustrated on a large scale. Fig. is an exterior side view of the construct-ion shown in Fig. 3. Fig. 5 is a plan view of the construction shown in Fig. 4t with the sack removed. Fig. (i is a detail or' the yieldable connection between the piniens and valve Stems.

A, indicates a portion of the Atelly of a wheel, and B, indicates a metal rim carried thereby, and well known in this art.

C, indicates a tire shoe of usual construction, and D-D etc. indicate separate sacks or inner tube sections, preferablyI made oit rubber or other suitable expansiblc ,iiexible material. These sacks are usually formed in cross section as illustrated in Figs. l and 2, and are provided on their under side with short tubular projections D.

E, indicates a casting of aluminum or other suitable metal, which is suitably split and is formed circular, its inner periphery fitting the outer surface 3 of the rim B, and the Casting may be sprung` laterally over: the side of the rinrto its position therein, as will be readily understood. The casting E is provided with a conduit E2 which extends from one end to the other, it being under'- stood that said ends are closed. is provided with .outwardly projecting nipples F13-E3 ctc. spaced evenly apart circumferentially of the tire, in lthe outer end of each .of which is formed a circular recess E4. A passage E5 extends from the conduit E2 to each of the recesses E4 and each passage is controlled by a valve F which is Acarried by a valve stem F having a thread formed thereon which engages with a thread formed in the nipple G which nipple is screwed into the casting E, and located between the casting E and the valve and nipple, is a compressible packing material H, such as cork, to hold the air from escaping when the valves F are open.

Mounted on one end of each of the valve stems F is a spur gear wheel i which is rotated by a rack J mounted on a 'band J, which band enteritis entirely around the rim B and'is preferably mounted on a laterali extending flange E of the casting E. band J is also provided with a rack J2 formed on one edge thereof, and a spur gear wheel l meshes with the rack J2 to rotate the band J to open and close the valves F, as w'iii be readily understood. The wheel K is mounted on a red M which is supported at its upper end by a bracket L, and the iower end of which extends through the band B, and telly A, and is formed with a square end M to permit the rod to be turned by means of a wrench.

N, indicates a metai tube provided with a cap N2 at its outer end which tube enteritis through the felly into the secured thereto by ribs N', and is in open communication with the conduit E2. This tube serves to hold the casting E to the rim B.

O, indicates a. metal shield which is semicircular in cross section and` is made in two or more sections to permit them to be placed on the rim, and extends cireuinferentialiy and covers the casting E as shown, its edges resting on the surface ll of the rim. This shield is provided with openings O to registerwith the recesses E4 in the casting E.

The spur gear I is provided with a recess I", and the valve rod 1*" is provided with a pin F2 which abuts one wall formed by the recess as shown, and a spring l) abnts the pin F2y and the opposite wall of the recess l, and, therefore, when the rack J is turned, movement is transmitted to the gear wheel I through the pin F2 and spring l) in the act The casting The fasting E and is of closing the valve lt", so that should one valve seat slightly in advance of another, the' rack can still l rotated lar enough to close the other mires, the springs l being` compresed mfa'e or lees to permit this actionA After the mechanical parts have been assembled, the sacks D are fastened to the portions lizs by placing` the tubular 'extensions D into the nuts l)2 and then forcing the 'nipple Dffinto position to clamp the portions D between the nipple D and nut D2, as willbe' readily understood. lifter the sacks 'listened in theiiespecth s rehave all been t eesscs E1 ivitli'their ends in proper relative position to each other, the rod ld is turned to open thel valves l? andthe shoe C is then placed inposition over the sacks and tastened to the rim B. rflic cap N2 is removed from the pipe N .and an. air pump is con lnected thereto and air forced i-,uto the conduit l'lg and flows therefrom through the respective passages'll' into the sacks l) until they are tally inflated under proper fpressure. rl`he rod ld is then turned to operate the valves l to close each ot the passages E5. In case one otv the sacks .D should become punctured, the sacks on each side thereot` .would inmediately expand due to the air pressure contained therein andf'tlully collapse the pnnctured sack and would occupy the space formerly occupied byl the punctured sack, thus keeping a lcompletely expanded shoe, as will be clearly understood.
